WIRE-FENCE MACHINE.

Specification of Letters Patent.

Patented 0st. 14, 1913.

Application filed January 31, 1913. Serial No. 745,308.

and useful instrumentalities and combinations in connection with wire fence machines, whereby the mechanisms usually employed will be greatly simplified, the resultant cost of the machine reduced, the product materially improved, the uniting of the wires in the formation of the fencing being thereby made more positive, secure, and properly justified and uniform, and the power required to drive the machine will be reduced to the minimum.

The primary object of this invention is to provide in one common organism, a wire fence weaving machine which may be so constructed as to utilize every particle of the material supplied thereto into a salable product, each portion and feature of which will have a distinct function.

In this invention the basic object is the provision of the two rollers whose function is to grip and justify the product as it is being formed, and which contribute to the formation of the product by holding one portion of each of the various twists or ties while the other portion thereof is being formed, thereby producing a more compact and uniform twist or tie and at the same time dispensing with a great amount of expensive mechanism which has been heretofore required. However there are other minor but important improvements, and various new combinations of parts shown in prior patents issued to me, but which are herein brought together in new combinations.

To these ends my invention is based upon certain mathematical principles, while they admit of all variations necessary in the complete and practical formation and justification of wire fencing, are, nevertheless, capable of being adapted concretely and their material results expressed in varying form by means of mechanisms adapted to operate in accordance with such principles.

which, i

The preferred means for carrying out the practical operation of the principles of this invention are shown most clearly in the accompanying drawings, in which Figure 1 is a front elevation of my complete machine, showing a portion of finished product in connection therewith. Fig. 2 is a sectional plan view of the lower portion of my machine, the same being taken as on line 22 of Fig. 3. Fig. 3 is a left-hand end elevation of the machine. Fig. 4L is a detail view showing a vertical section as taken centrally through certain of the twisters and the associated mechanisms, showing the relative position of the rollers thereto. Fig. 5 is a right-hand end elevation of the machine. Fig. 6 is a detail view showing the cam and its mechanism for shifting the twisters. Fig. 7 is a front elevation of a portion of the bed-plate, certain of the twisters, and the two rollers, also showing the supply wires, and a port-ion of the finished product prior to its being crimped. Fig. 8 is a perspective detail view showing the left-hand end-portions of the rollers and their bearings. Fig. 9 is a detail view, in horizontal section, showing the right-hand end portions of the rollers and their bearings. And Fig. 10 is a detail edge view of the bulldozer-cam alone, showing means for its attachment.

Similar indices denote like parts throughout the several views.

In order that the construction and the several operations of my machine may be better understood and appreciated, I will now give a detailed exposition thereof, in which I will set forth the several features of the invention as comprehensively as I may.

The frame of the machine comprises the right-hand end member A and the left-hand end member B, which extend up vertically and they are spaced some distance apart and parallel with each other. Said members are rigidly connected together by the sill T, the cross-tie U, and the bed-plate 16. Extending through the members A and B, mounted in suitable boxings, is the main shaft 1. Secured on shaft 1, to the right of member A, is the gear-wheel 2; also secured 011 shaft 1, to the right of wheel 2, is the pinion 3. Mounted on the face of member A is the bracket 4 which carries the stubshaft 5. Mounted on the outer end of shaft 5 is the pulley 6 by which power may be applied to the machine through the medium of a belt (not shown), which may be connected to a motor. Also mounted on shaft 5 is the pinion 7, which is in mesh with gear-wheel 2. Mounted on top of the respective members A and B are the bearings A and B in which is revolubly mounted the bulldozer shaft 8, the latter extending from end to end of the machine. Mounted on the shaft 8, to the right of member A, is the large gear wheel 9; and mounted on shaft 8, between gear-wheel 9 and member A are the two frictional-contact sprocket-wheels 10 and 11. Secured on the outer face of member A is the head 12 which carries the stub-shaft 13, on which latter revolves the large gear wheel 14 which meshes with said pinion 3. Also mounted on shaft 13 and formed rigid and concentric with wheel 14 is the pinion 15 which meshes with said gear-wheel 9.

The buZZcZ02er.-Said shaft 8 forms the core of the bulldozer and carries the various parts thereof. Secured on shaft 8, between members A and B, are a plurality of comparatively large disks 44, 45 and 46. Located adjoining each other, side-by-side, are a plurality of sets of bars which are parallel with the shaft 8, the members of each set comprising the bars 47, 48 and 49. Each set of bars is spaced some distance apart from the sets next thereto as shown. The two outermost bars of each set, that is bars 47 and 49, are rigidly secured to the peripheries of the disks 44, 45 and 46, while the central bar, 48, is adapted to slide endwise between the other two. Mounted on the right-hand end of each of the bars 48 is a roller 50 adapted to engage the fixed-cam 21 to move the bars 48 to the left at each revolution of the bulldozer. The fixed-cam 21 has two outwardly extending plates, 21 and 21", which are adapted to stride the boxing A, and to be adjustably secured to the upper end of the member A by the two bolts 7 2 and 73. The slots :0 and y which are formed through the respective plates 21 and 21 are adapted to receive therethrough the re spective bolts '72 and 73 thereby allowing the cam 21 to be adjusted laterally. Threaded horizontally through the web of the cam 21 are the two set-screws 74 and 75, the points thereof being adapted to impinge against the inner face of the member A and thereby brace the cam 21. Said set-screws also aid in setting the cam: The bolts 72 and 73 may be loosened and then by turning said set screws the cam 21 may be drawn to the left as desired.

From the above it is manifest that the amount of crimp given to the product may be varied as desired by simply changing the position of the cam 21 to the right or to the left. Said cam 21 is in the nature of a disk which is secured around boxing A with the shaft 8 passing centrally through it. Said cam has two flanges, a and b, for the rollers 50 to engage with, the former for forcing the rollers to the left and the latter for forcing the rollers to the right. For each of the linewires to be carried up over the bulldozer there is a set of three pins, designated 11,, 0 and p, projecting out from each set of bars 47, 48 and 49, respectively.

From the above it is apparent that if the bar 48 is located at its limit of movement to the right, that a line-wire passing up over the bulldozer may rest between the pins np and 0, and then when the bulldozer is turned the roller 50 will engage the flange a of the cam 21, forcing the bar 48 to the left, thereby causing the pin 0 to engage the line-wire and press it tightly against pins n and 7), thereby gripping the wire and crimping it laterally, holding it with such force that as the bulldozer continues to revolve the line-wire will be drawn upward. After the bulldozer has turned a certain amount then others of the bars 48 will be operated in like manner to engage the linewire, the bar just referred to then being released by reason of the roller 50 engaging the flange 1) thereby moving the bar 48 to the right. Said operations, of course, follow each other continuously, and operating in like manner upon each of the line wires of the fence as it moves upward over the bulldozer.

ReeZ.Mounted in suitable bearings, a and Z), carried on the rear extensions of the respective members A and B, is the reel which includes the two stub-shafts 0 and c which operate in the respective bearings a and Z). Secured on the inner ends of the respective stubs c and 0' are the heads 0 and 0". Removably mounted in and connecting the heads 0 and 0" are the half-round bars N and 0, around which the finished product of the machine is to be wound.

Secured on shaft 0, to right of member A, is the large sprocket wheel P, and the small sprocket wheel Q. Sprocket-wheel P is connected to sprocket-wheel 10 by the sprocket-chain R; and likewise sprocketwheel Q is connected with sprocket-wheel 11 by the sprocket chain S.

BccZ-plate.The bed-plate is designated by numeral 16, as stated, and extends across the front part of the machine, being secured at each end to the end-members A and B. The bed-plate is formed hollow, with an opening in the back thereof. On the bedplate are mounted the various twister mechanisms hereinafter referred to.

Twister operating mcchanism.-Mounted on the left-hand end of shaft 1, that is to the left of member B, is the gear-wheel 17. Numeral 18 denotes a stub-axle extending out some distance from the face of member B, being secured in a head not shown, and it is located directly above shaft 1, as shown in Fig. 3. Formed integral or connected and concentric with each other are the pinion l9 and the bevel-gear wheel 20 which are mounted to revolve on said axle l8. Bevelgear 20 faces inward; and pinion 19 is located in mesh with gear-wheel 17 Carried in suitable boxing, as the boxing 100, secured to the face of member B, is the shaft 22 which is located at right-angles to shaft 1, and on same plane as axle 1S. Mounted on shaft 92, to the rear of bevel-gear 20, is the corresponding bevel-gear 23 which meshes with bevel-gear 20. Secured on the forward end of shaft v22 is the pitman-wheel 24, Openings are formed through member B allowing bevel-gear 23 and the pitmanwheel at room in which to operate and with the shaft 22 located near to member B, as shown. irdjustably pivoted to the face of said pitman wheel is the pitman 25, connected by the pitman sleeve 25. Also adjustably connected to the inner end of the pitman is the inner pitmansleeve 25. Slidably mounted inside the bed-plate 1G and movable longitudinally thereof is the rackbar 26 which has its central portion cut away in order to provide the two oppositely disposed ofset racks e and c, the former being at a higher elevation than is the lat ter. Mounted at the center of the rear edge of the raclcbar 26 is the hanger 27 to which is pivoted the inner pitman-sleeve 25". Secured on shaft 1, near member A, is the camwheel 28, which has a cam-channel (Z formed in its right-hand face, shown in Fig. (3. Mounted on pivot 29, which is secured to the inner face of member A, is the upwardly and rearwardly extending arm 30, the two parts thereof being at right-angles to each other.

Numeral 31 denotes a link which is con nected at its rear to the angle in the arm 30. The rear end of arm 30 carries a camroller 32 which operates in said cam-channel (Z. Secured on the forward face of the bedplate 16 are the three hangers 33, 3d: and 35. Mount-ed to rotate in said hangers is the shaft Secured to the right-hand end of shaft 36 is the downwardly extending arm 37, the lower portion of which is pivoted to the forward end of said link 31, by the adjustable pivot 101, as shown in Fig. (3. Secured to and extending rearward from shaft 36 are the arms 38, 39, a0 and etl. Carried by the rear ends of all of said arms, and extending along underneath and parallel with the bed-plate, is the fiat-bar 42, by which the twisters are shifted as the camwheel 28 revolves.

T wiszcrs.Formed through the upper member of the bed-plate is a line of apertures, in each of which is rotatably fitted a stem which forms the body of a twister, each of said stems being denoted by numeral as. In this instance the several twisters, of

which the said stems form the basis are identical with each other, except in a few minor particulars, therefore one description will answer for all and they will be described collectively as near as possible. Said stems as are each retained in place by a collar 43 which rests on the surface of the bed-plate. Said stems are formed hollow, and neatly fitting therein is a tube 64:. The upper portion of said stems flare out thereby forming a head 43 which has a flat upper face. Secured on the lower end of each of said stems as is a ear wheel 65 each having a shoulder forming a collar on one side, the collar in each alternate gear being directed up while the others are turned down, thereby causing each alternate gear to mesh with rack e, and the others with. rack e, from which it is apparent that as the rack-bar is moved endwise said stems will be rotated, each alternate stem to the right, the others to the left, alternately. Said tubes Get extend down below the stem 43, each being dis posed through an aperture therefor in the lower portion of the bed-plate, and they then extend through suitable apertures in the shift-bar to which they are secured by lock-nuts, as shown in the lower portion of Fig. l. A feed aperture is formed longitudinally through each of the tubes 64 through which the linewire material is fed to the respective twisters. The heads dQ are all located on the same plane and remain so at all times, there being a space between each two heads. At two opposite points in the periphery of each of the heads there are formed the two segmental notches or indentations 7L and h. Secured across over the top of each of the heads l3 an arch member 66, through the center of which is an aperture in which operates the wire H. Formed through the center of each of the heads te at right-angles to and underneath the arch 66, is an elongated aperture, for the purpose hereinafter stated, the same being in line with said two indentations 7L and it, that is, the ends of said elongated apertures point to said indentations. The upper end of each alternate tube (34; is somewhat different from the others: One set having formed on its upper end a cross-bar G l having at each end a downwardly extending lug 64, and also below said cross-bar and formed integral with tube 64 is a key 64 which fits in said elongated aperture to prevent the tube from turning but allowing it to move up and down. The upper ends of the other alternate tubes 64 have the crossbars or carrying at each end the upwardly projecting lugs Gat The cross -bars (34E are located on a higher plane than the cross-bars 64 but all are adapted to be moved up and down in unison. A plurality of disks G7 are provided, there being one for each twister-head, and

each of said disks has a peripheral upwardly and a downwardly extending flange thereby forming a rim entirely around on each disk. Extending down from the center of the disk is a hollow nipple 67 and said nipple also extends upward above the disk to form the upwardly flaring cup 67. Said disks are adapted to be transferred from one to the other of said heads as follows: Each of the heads 63 is adapted to be rotated by said racks, moving first to the right and then to the left, each alternate head being rotated opposite to that of the head next thereto. As an instance,in Fig, 7 the first head to the right is shown as in position to rotate to the left while the head next thereto is rotating to the right, the latter carrying the two disks 67, there being a stay-wire 1 extending up through one of said disks and a stay-wire J extending up through the other of said disks. As indicated, the second head carrying the two disks has already made one revolution to the right, and it is so geared that it will make another revolution to the right, thereby twisting the wires 1 and J around the line-wire H. After the wires 1 and J have been twisted twice around wire H in one direction then the reverse movement of the rackbar will cause the heads to rotate in the opposite direction, thereby twisting the wires I and J around wire H in the opposite direction from that first mentioned, and at the same time unwinding the wires 1 and J from around stem 43. Now when the disks have been returned to their first positions then two of the notches in the heads, one of the first and one of the second head, will be opposite to each other with the stem 67 inclosed thereby. New at this time the pitman 25 will be on dead center at one limit of its stroke and at the same time the cam-wheel 28 will be in such position as to slightly turn shaft 36 causing the bar 12 to be raised which will lift all of the stems 6 1-, thereby withdrznving the lugs 6 1 from the rims of disks 67 and at the same time causing the lugs 64 to engage said rims of the disks. Now it will be apparent that the first twister to the right will carry two disks and the other next thereto will be the idler the same as the first twister was in the action first described, thereby causing the two wires 1 and J to be changed to the first and third twister and then completing the function of twisting K-J and 1L around the respective third and first line-wire H, after which another transfer will take place as above stated, in which the heads then carrying two disks each will deliver them to the adjoining heads, delivering one disk to the right and the other to the left, thereby causing the second twister to take one disk from the first head and another from the third head, and so on, which will transfer wire I, for instance, to be twisted from the first around the second wire H, while wire J will be transferred from the third to the second wire H, and in like manner wire K, will be transferred from the third to the fourth wire H, and wire L will be transferred from the next line-wire to the left to the fourth line wire.

The twist h0ZcZer.In order to hold the several twists while they are being formed, particularly holding the upper part of the twist while the lower portion is being formed, I provide a mechanism which is entirely new, and which is the most novel fea tures of this present application. Carried by the members A and B, and extending centerward therefrom, are the respective brackets 102 and 108 which are oppositely disposed with relation to each other, the former being secured to member A by the bolts f, f and f; and the latter is secured to member B by bolts 9, g and g. Rigidly secured on the inner face of each of said brackets 102 and'103 is the respectvie boxings 10 1 and 105. Numerals 106 and 107 denote the two blocks which neatly fit in boxing 104:, and they are adapted to slide forward and backward therein and blocks 108 and 109 in like manner are located in boxing 105. The blocks 106 and 107 are adapted to be resiliently clamped together, and to the rear limit of their respective movements, by the helical spring 110 which presses against the forward face of the block 107 and against the forward end of boxing 10 1. Threaded through the center of the forward end of boxing 104 is the stem 111 on the outer end of which is the hand-wheel 112. In like manner the blocks 108 and 109 are adapted to be resiliently clamped together, and to the rear limit of their movement, by the helical spring 113 which presses against the forward face of the block 109 and against the forward end of boxing 105. Threaded through the center of the forward end of boxing 105 is the stem 1141 on the outer end of which is the handwheel 115. The blocks 106 and 107 may be adjusted as to their rearward limit of movement by the adjusting screw 116; and in like manner the blocks 108 and 109 may be adjusted by the adjusting-screw 117. Pivoted in and extending between the blocks 106 and 108 is the rear roller 118; and pivoted in and extending between the blocks 107 and 109 is the front roller 119. Said rollers are adapted to be resiliently clamped together by the springs 110 and 113, the degree of tension being regulated by the hand-wheels 112 and 115. The arrangement is such that the product as it is being formed passes up between said rollers, which is for three reasons: That they may hold the upper portion of each twist or'tie while the lower portion thereof is being formed; to justify and harmonize the product; and to press the twists or ties tightly in engagement with the line wire around which they are formed.

Gum-(Z raz'Z.Extending along in front and parallel with the shaft 86 is the guard-rail 120. Said guard-rail is carried by the auxiliary hangers 121, 122 and 123 which are in turn carried by the respective hangers 33, 34 and 35. lhe said guard rail will protect the operator from getting in contact with shaft 36, but more particularly it prevents the supply stay-wire material from springing out beyond the front of the machine, they being carried up between the guard-rail 120 and the shaft 86, and are thus retained in proper position to be delivered to their respective twisters.

Guides for the line wircs.Secured near the ends and to the face of the sill T are the two hangers 68 and 69 which carry the stationary rod 70. Revolubly mounted on the rod 70 are a plurality of sheaves 71, one for each line wire, by which the line-wires are guided in order to deliver them to the respective twisters 64.

Modes 0pemmZi,In practice the various parts and mechanisms of the machine are timed to operate in accurate succession with relation to each other in order to accomplish a unitary result at each cycle or impulse of the machine, the various movements following each other and then repeating these movements to form a continuous operation while the machine is in operation.

The machine may be threaded by bringing the various line-wires from their sources of supply in front of the machine back under and up in contact with their respective sheaves 71 and then up through their respective tubes Get, through their respective arch members 66, then over the bulldozer, and finally securing their ends to the bars N and O of the reel in the rear. Also separate stay-wires are brought to the machine, each from a separate source of supply, bringing them up between the shaft 36 and the guardrail 120, and then up through their respective disks 67, from which thev are drawn up and each is secured to a line-wire H. Now when the machine is started the linewires will be wound on the reel in the rear, followed soc-n after by the completed fencing, also the wires will be grasped by the bulldozer, and by reason of the construction of the bulldozer as set forth, the product will be crimped laterally thereby, besides contributing to advancing the product at the required rate of speed.

As the machine is operated the various twisters will perform their various functions as hereinbefore set forth, each forming a double or compound twist at each intersection of the stay-wires with the line-wires.

As the wires move upward between the rollers 118 and 119 it is evident that the product will be flattened and evened said rollers being so located that the upper portion of each twist or tie will be located between the rollers while the lower portion of the twist or tie is being formed. It is also evident that said rollers or their equivalents may also be employed for the same purposes upon other styles or types of fencing, and in connection with fence-machines of other makes and with equal advantage thereto.

Having now fully shown and described my invention and the best exemplification thereof to me known at this time, what I claim and desire to secure by Letters Patent of the United States, is

1. In combination with a wire fence machine having means for forming a double twist at each intersection of the line-wires and the stay-wires, a pair of rollers between which the product passes as it leaves the twisting means and adapted to hold the first port-ion of each twist while the second portion thereof is being formed.
